External fixing device of protective net body, protective net fixed externally and application of protective net

Abstract

The invention discloses an external fixing device of a protective net body. The external fixing device comprises stand columns with the lower ends fixed to the ground on the periphery of the net body. A suspension arm is fixed to the upper portion of each stand column, extends in the normal direction of one joint point of the upper end of the net body and enables a safety distance to exist between the stand column and the net body, and the other end of each suspension arm is used for being detachably and fixedly connected with the upper end edge of the net body. The invention further provides a corresponding protective net and application thereof. The protective net body is reliably supported and fixed; the horizontal safe distance between a supporting element and the net body can be determined according to needs, and it is guaranteed that the supporting element cannot cause any damage to personnel or animals in the net; and the protective net has the characteristics of being simple in structure, convenient to mount and dismount, safe and firm. The external fixing device of the protective net body, the protective net and the application of the protective net are applicable to occasions which have requirements for trampoline enclosures, net enclosing protection of livestock and poultry farms, net separation of sporting venue areas, enclosing of prisoner activity spaces, defining of animal and bird venues of zones, interpopulation isolation of animal parks and the like.

Description

technical field [0001] The invention relates to a net-shaped protective device, in particular to an external fixing device for a protective net body, a protective net fixed outside the net and applications thereof. Background technique [0002] In daily life, such as the enclosure of trampoline for children's entertainment, the net enclosure protection of livestock and poultry farms, the mesh isolation of sports venues, and the enclosure of prisoners' activity spaces in prisons, etc., protective nets are often used structure. Since the net space in these places is mostly used for the activities of people or animals, when installing and fixing the net body, it is necessary to consider that possible physical damage to people or animals should be avoided as much as possible, such as trampoline, sports fields, etc. If the actions of the activists in the net are impactful, rigid devices should be avoided in and around the net; and there should be no hard objects in the prisoner'...

AI Technical Summary

Problems solved by technology

The support method in this product patent is only suitable for the small area of ​​the surrounding area, because of the existence of the buffer device, it is not suitable for large-scale venues, especially not suitable for the situation where the net body shakes frequently. In addition It will also bring challenges to the strength of the support rod due to the large area of ​​the enclosed area, especially because of the stability of the mesh body, it will bring great safety hazards to the overall device
